How to create shortcut command

Cisco IOS permits to define a shortcut to complex command. An alias can be configured to do anything that can be done at the command line, but an alias cannot move between modes, type in passwords, or perform any interactive functions.

To create a command alias, issue the alias command in global configuration mode. The syntax of the command is alias mode command-alias original-command. Who have never typed repeatedly the commands show cdp neigh or show ip inter brief?

Some helpful alias could be:

scn -> show cdp neighbor

command: alias exec scn show cdp neighbor

ifconfig -> show ip interface brief

command: alias exec ifconfig show ip interface brief

sint [interface number] ->show run interface fastEthernet

command: alias exec sint show run interface fastethernet

proc -> show proc cpu | excl 0.00%__0.00%__0.00%

command: alias exec proc show proc cpu | excl 0.00%__0.00%__0.00

eth0 -> interface fastethernet0/0

command: alias configure eth0 interface fastethernet0/0

ns -> no shutdown

command: alias interface ns no shutdown

Tips: if you would create an alias for ‘interface mode’ and ‘priviledge mode’, you must define the same alias for the two environment. See you below:
